It's bizarre to me that harcore vegans want to own a pet to begin with. Keeping bees for honey is bad, but separating a kitten from its mother at an early age and castrating it for your convenience and deciding how they live (restricted to an apartment or not) is totally fine?

I understand that most pets live a good life, but man, I can't bring myself to make choices like these. I mean there are ways to circumvent it (get an older cat from an asylum for example) but it doesn't really remove the "pet dilemma" to me.

I understand why vegans would be unhappy with that answer but it is the way it is.

I don't. Veganism is about the fact that humans can live without animal products, which is true. Not accepting that actual carnivores exist, even being unhappy with this means you're well in extremist nutjob territory.

I am a vegan. While my dogs were alive they ate meat as well as veggies. It seems to me that a lot of vegans don't realise that it's a scale and not binary. The whole philosophy of veganism is "as much as you are able" so I guess there is extremism everywhere.

I'm vegan and I don't know why these "vegans" are towing the line to to include non-human species. It's just as gross for vegan humans to apply their values to values in a dominant manner as it is for non-vegans to. Literally vegans doing this is antithesis to the entire cause.

I'm glad they got slapped. You'll always have idiots in a movement I guess...

It's a microcosm for science denial or misunderstanding of all kinds. Vegan cats and antivax may not seem related but the underlying misinformation is not dissimilar.

I tried following up on the vegan cat research being posted and it was very difficult to get a solid answer. There are multiple brands of vegan cat food marketed and sold, and it isn't outrageous to believe that our industrial society could find an ethical way to source the necessary nutrients and enrich the cat food.

But also there's very few studies that test the claims of the vegan cat food. What few meta-analysis exist, and anecdotes online, would suggest that all those foods lack certain critical nutrients for long-term feline health. But the anecdotes are drowned out by well-intentioned people who want to believe it works, and the studies are small, rare, hard to read, and locked behind paywalls.

Why do people even try to keep cats on vegan diet? It was your fucking choice, not the cats.

Im vegetarian, my cat eats meat. Im not gonna force anything on him unless he comes to me and tells me he wants to try it.

A lot of vegans will hate this, but YOU'RE NOT A FUCKING SCIENTIST! Drop all the journals and research you want, but your pet is not a lab-controlled experiment. Besides, something being in a journal doesn't make it true. If it is regularly cited as true, and has swept into general understanding of how to feed a pet, then it's factual...

I'm all for vegans living their best lives. Don't force it on a pet that doesn't know better. Vegans harming animals through their own food choices isn't a new thing, ask most vets and they'll have seen the effects of malnutrition from someone that thought that they knew better.

The reason cats can't be vegan is that they cannot produce an amino acid called taurine, which is something dogs and humans can produce (but which we also get sometimes from dietary sources).

Most dietary sources of taurine are meat. This is why dogs and humans "can be vegan" but cats "can't". However, vegan taurine is made and can be bought as a supplement, both for humans (if you want to ensure you get some taurine in your diet), but also in properly made vegan cat food.

It seems to me then that cats can be vegan, just not without intentional effort to ensure proper supplementation of taurine. That is, they couldn't be vegan in the wild (where the only source of taurine is meat) and you can't just start to feed them a vegan diet without taurine and expect the cat to be healthy and survive.

In fact, cats fed a proper vegan diet tend to have better health:

I think the question is really what you are feeding your "vegan" cat: if you have managed to find (or make) a properly fortified vegan cat food it is theoretically possible to feed your cat a vegan diet.

This all feels a bit like the "controversy" around feeding young children and babies a vegan diet: done poorly it can be catastrophic (pun not intended), but it's entirely possible to have a healthy vegan diet when enough effort is put into ensuring nutritional needs are actually satisfied.

That said, I also know of two other vegan responses:

1. for some vegans, having pets is not vegan to begin with, so a "vegan cat" is a contradiction in terms even if you fed them a vegan diet, you still wouldn't be an ethical vegan by owning a cat. This is admittedly a less commonly held view which centers ethical veganism on the rights of animals to have autonomy, which if plausible in some ways seems at least impractical in the case of domesticated animals. There are questions of the harm that might be caused by choosing to treat cats not as pets but as autonomy-rights-bearing "wild" animals, but those ethical vegans might rightly point out this doesn't undo the cat's rights and the practical questions should be handled separately.
2. most vegans I know IRL just feed cats a non-vegan diet, acknowledging it is safer and more reasonable for their cat than trying to figure out a way to feed them a vegan diet. Good vegan cat food isn't that common or easy to find as far as I know, and I assume it would be outrageously expensive.

Well put. Cats are OBLIGATE carnivores. They do not have anatomy to support extracting necessary nutrition from vegan sources that are available. It IS hypothetically possibly for them to survive and thrive on an engineered food source but, such a thing does not currently exist and the chemical complexity makes it unlikely in the near future.

this is hilarious, and 100% on brand for a vegan community.

Making dogs vegan still doesn't sound like a good idea to me tho

Disclaimer that I'm not even a vegan but you're spreading disinfo here to make vegans seem completely unreasonable. I suggest anyone check out the actual discussions instead of trusting this summary.

For the record, science disagrees with you. According to an analysis of all current research, there is no statistically significant difference of cat heath when fed a nutritionally sufficient vegan diet. Of there is a similarly high quality study that finds that a nutritionally sufficient vegan diet is worse for cats I would love to see it.

The vegan diet we are talking about isn't a bunch of vegetables, it's a manufactured dry food specifically designed to have all the nutrients a cat needs.

People often use the obligate carnivore excuse, but use it in an unscientific way. Obligate carnivores have nutritional needs that can only be meet through meat in the wild, but humans are perfectly capable of manufacturing these nutrients. We are so good at it that we supplement these synthetic nutrients in meat based cat food already.

This is a contentious issue for most people, and it can be hard when you are very passionate about something to look at the evidence and change your opinion. I've looked at a decent number of studies on the topic recently, and they all seen to point to the conclusion that a diet without meat can be healthy for cats, so long as it contains all the nutrients they need.

Thank you for the summary! I found myself in OP. I am eating mostly vegan, and I have a cat, and I believe people who force a vegan (or even vegetarian) diet on their cats need mental help.

Cats have dietary needs that would require them to eat meat in nature. But we can make vegan, synthetic food that meets these needs. In fact, studies have shown that cats on vegan diets tend to be healthier if anything.

I don't understand why people upvote summaries that don't even try to be objective. I honestly think the mods there do notably abuse their power to remove comments, but let people decide that for themselves. This commenter is telling you who to support while being confidently incorrect on the original issue.
